R2 values for adiponectin analyses ranged from 0.33 to 0.41 with leg fat mass having the highest R2.
R2 values for apelin analyses ranged from 0.08 to 0.09, indicating low goodness of fit across all analyses.
All coefficient estimates are from multiple linear regression analyses with body composition measures as a continuous variable. Analyses were conducted individually for each measure of body composition. All estimates for adiponectin analyses are adjusted for age, race, and sex. Estimates for lean mass and lean mass index are adjusted for age, race, sex, and fat mass. Estimates for variables of fat distribution (leg fat mass, trunk to leg fat ratio, and visceral fat mass) were adjusted for age, race, sex, and fat mass excluding the variable of interest. In addition, all estimates for apelin analyses are adjusted for VO2 maximum. Bolded values indicate significant findings.
Variable was natural log-transformed for analyses.
